Working out the receiver, switch, battery and throttle servo locations. The battery and throttle servo still need to be mounted, but their locations are shown .

I made a tray to hold the receiver and located it directly beneath the pilot station. I glued in plywood pads to mount the rx tray. I am using a Futaba 617 rx so I needed to fabricate something to hold the antennae in place and away from other wiring. As you can see, I am using Velcro to hold the rx to the tray.

With this receiver location I won't have to use any servo extensions for the throttle, rudder or elevator servos.

And a shot of the tray arrangement for the tank as well as a picture of the battle tested Zenoah 445 twin.
